Abstract

A numerical investigation of mixed convection from a horizontal cylinder in a saturated porous medium is presented. The governing equations based on Darcy’s law are expressed in a body- fitted coordinate system and solved numerically by explicit method. The direction of the flow varies between the vertically up ward(assisting flow) and vertically downward(opposing flow). Results are presented for Reynolds number Re from 10 to 100 with Grashof numbers up to Gr =5Re. The Prandtl number was kept at a constant value of 0.7. results are presented for the streamlines and isotherms as well as the local and average Nusselt number at different values of governing parameters. Comparison with previous theoretical results show good agreement.
